Have you checked your auto's tires lately?

Many of us are so busy, that we forget to check our autos tires for the correct air pressure and overall condition of each tire. This may sound like a lot of work for you, but stranded on the side of the interstate, with a flat, can be flustrating as well as dangerous. Question: when was the last time you checked the air pressure in your autos tires? Have you ever had a flat in a dangerous location? Was this your fault?
